A² - ab + 8b + b² - 1
There are 5 terms in the expression.
a² = 1st term
ab = 2nd term
8b = 3rd term
b² = 4th term
1 = 5th term
Each term is separated by a plus (+) sign or a minus (-) sign.
A term is either a number, a variable, or a number and a variable multiplied together.
a², ab, b² are variables.
8b is a number and a variable multiplied together
1 is a number.
Answer:
Now, 3x 2+x+5⩾0
This is because b² −4ac=1−4×5×3
=−59 (roots are imaginary)
3x²+x+5=(x−3)² =x²+9−6x and x−3⩾0
2x²+7x−4=0
2x²+8x−x−4=0
2x(x+4)−1(x+4)=0
(2x−1)(x+4)=0
x= 1/2 and−4 but x≥3
∴ No solution.
lol hehehe
Answer: 78.75
its just multiplying the extra 25 cents they added by the number of tickets they sold(315) and that equals 78.75$

Answer: 0.6</h3>
Work Shown:
tan(angle) = opposite/adjacent
tan(30) = x/1
x = tan(30)
x = 0.57735 approximately
x = 0.6
